Flexible anchor delivery system

Abstract

An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

What is claimed is: 
     
       1. An assembly comprising:
 a flexible fixation member comprising a body having two terminal ends; 
 a suture passing through the fixation member at various points along a length of the body between the terminal ends such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site; and 
 a delivery device comprising:
 a tubular member; 
 an elongated inserter slidably disposed within the tubular member, the inserter comprising a forked distal end and a proximal end, the forked distal end configured to receive a portion of the fixation member and the suture therein; and 
 a finger-engageable trigger fixedly coupled to the proximal end of the inserter and configured to advance and retract the inserter relative to the tubular member, the trigger comprising a retention member for retaining a proximal end portion of the suture; 
 
 wherein the delivery device further comprises a handle to which the trigger is slidably coupled; and 
 wherein the handle defines first and second openings in a distal end of the handle configured for passage of the suture therethrough, the first opening positioned distally with respect to the second opening. 
 
     
     
       2. The assembly of  claim 1 , wherein the delivery device further comprises a button coupled to the trigger and the handle and configured to permit the trigger to slide relative to the handle when the button is depressed. 
     
     
       3. The assembly of  claim 2 , wherein the handle defines a plurality of cutout portions along a length of the handle, the cutout portions configured to receive a portion of the button therein to fixedly engage the trigger to the handle. 
     
     
       4. The assembly of  claim 1 , wherein the trigger further comprises a circumferential groove defined about a periphery of the trigger. 
     
     
       5. The assembly of  claim 4 , wherein a length of the suture is wrapped about trigger at least once and is retained in the groove. 
     
     
       6. The assembly of  claim 4 , wherein the trigger further defines a slot configured to receive a portion of the suture therethrough and direct the suture into the groove. 
     
     
       7. The assembly of  claim 1 , wherein the trigger comprises a substantially cylindrical body and a pair of finger-engageable elements extending laterally from the body. 
     
     
       8. The assembly of  claim 1 , further comprising a cover disposed over the retention member. 
     
     
       9. The assembly of  claim 1 , wherein the suture passes from an interior to an exterior of the handle through the first opening and the suture passes from the exterior to the interior of the handle through the second opening. 
     
     
       10. The assembly of  claim 1 , wherein the suture passes from an interior to an exterior of the handle through the second opening and the suture passes from the exterior to the interior of the handle through the first opening. 
     
     
       11. The assembly of  claim 1 , further comprising a cover element releasably coupled to a distal end of the handle and fixedly coupled to a proximal end of the tubular member. 
     
     
       12. The assembly of  claim 1 , wherein the suture passes through the fixation member to form two substantially parallel tail sections of suture. 
     
     
       13. The assembly of  claim 1 , wherein the fixation member is non-tubular. 
     
     
       14. The assembly of  claim 1 , wherein the fixation member and the suture comprise a size 2 suture.
